Abstract
The invention belongs to the technical field of chemical synthesis, and particularly relates to a water-soluble environment-friendly special material for a mulching film. The water-soluble environment-friendly special material for the mulching film is prepared from the following raw materials in percentages by weight: 50 to 55 percent of PVA (Polyvinyl Alcohol), 30 to 40 percent of starch, 1 to 10 percent of deionized water, 5 to 15 percent of polyethylene glycol, 1 to 5 percent of glycerol, 0.5 to 2 percent of triethyl citrate and 0.5 to 3 percent of carboxymethyl cellulose. A made product is flexile, smooth, oil-resistant, solvent-resistant and abrasion-resistant, and is good in gas permeation resistance and wide in application; the prepared product is excellent in performance, few in use level, low in cost and easy to produce; the strength, the transparency and the like of a film can be enhanced.
Description
Technical field
The invention belongs to technical field of chemical synthesis, and in particular to a kind of water-soluble environment protective ground film special material.
Background technology
Starch-based degradable plasticses are starch by being processed with other polymers blending after modified, graft reaction
A kind of plastic product, can industrially replace general general-purpose plastics etc., can serve as packaging material, packing, food
Container, toy etc..PVA is uniquely can be by bacterium as carbon source and the polyvinyl of using energy source, in bacterium and the work of enzyme
Under, 46 days degradable 75%, belong to a kind of Biodegradable polymer material, can be mass produced by Non oil-based route, valency
Lattice are cheap, and its oil resistant, solvent resistant and gas barrier property are outstanding, have unique advantage in terms of food, Key works Drug packing.PVA's
Using based on solwution method, thin-film material is prepared by casting film-forming.
And now with the development of agricultural, the use of mulch film is increasingly popularized, usable floor area is also increasingly wider, but white
Pollution is also increasingly severe, the cotton of such as establishing in large scale is required for using mulch film in planting process, but using terminating
Mulch film has all been stayed in ground afterwards, causes serious white pollution；
Certainly also there are some degradative plastic films on the market at present, but degradation effect and bad, it is impossible to purpose is effectively realized, is dropped
The solution cycle is also very long, does not reach expected environment protecting.
The content of the invention
Not enough according to prior art, the technical problems to be solved by the invention are：There is provided a kind of water-soluble environment protective mulch film special
Materials so that starch and PVA are organically combined, and product functionality is excellent, it is also possible to which effectively degraded, environmental-protecting performance is very good, drop
Solution period ratio is shorter.
Water-soluble environment protective ground of the present invention film special material, is made up of the raw material of following percentage by weight：
Described PVA is one or more in PVA17-88, PVA17-99, PVA20-99 and PVA20-88.
Described starch is cornstarch, tapioca or starch from sweet potato.
Described molecular weight polyethylene glycol is 200-10000.
The beneficial effects of the invention are as follows：
1st, obtained product flexible smooth, oil resistant, solvent resistant, abrasion performance, gas barrier is good, widely used；
2nd, starch can effectively be degraded, and not result in environmental pollution；
3rd, the properties of product for preparing are excellent, and consumption is few, low cost, easily production, can strengthen film-strength, transparency etc..
